After a couple of so so episodes Dr Who comes back with a belter.
Loved the Sontarans in the 70's with the 4th Doctor (Tom Baker) and now they have come back smaller and uglier than ever.

The 'spud heads' a militaristic society obsessed by war from the planet Sontar of the "southern spiral arm of the galaxy", seem to have a complex about there height.

This two parter sees the return of Martha Jones and the Doctors association with UNIT. The story line is good and the visualization of the Sontarans doesn't divert much from the originals.

Can't wait till next week.
